The IKEA effect works for architectural design

I've turned my focus from residential design, but here's a neat concept to keep in mind, when figuring out how to make a difficult process appeal to people...the IKEA effect.

When people construct products themselves, from bookshelves to Build-a-Bears, they come to overvalue their (often poorly made) creations. We call this phenomenon the IKEA effect, in honor of the wildly successful Swedish manufacturer whose products typically arrive with some assembly required.

I certainly found this to be true in my practice; allowing the homeowner to make as many (guided)  decisions as possible made the entire design process flow much more smoothly, and moral through some really difficult projects stayed high.
